I am about to install my 1st system and my friend said I would need a capacitator because my stock alternator is probably weak. Is this true?

I am running 700 Watts RMS... Will I have problems with lights dimming? will there be a huge drain on my battery? or will I need to buy a high output alt?

I do not really want to buy either one... but I do not have my system installed yet so I do not even know the problems I may have. How powerful is a stock contour alt? I heard it was 130 amp alternator... is that correct? Will that be able to handle me putting out 700 watts without any problems in my cars electrical system? Will I need to upgrade wires?

lol, so many questions. I am just confused. Will I have any of these problems? Any help is appreciated.
